As we have started to discuss them. I met another Brit transplant at Universal Studios, an electrician, he said that US electrical systems are similar to European ones from the 1930's. From my own plumbing point of view I still can't get to grips with burying water pipes in concrete. Down in Florida you will not find any service connected to a domestic property that is buried more than a foot deep....mostly only 6 inches deep. When I had the phone installed the guy buried the cable the way that we used to bury genny cables on exercise, about three inches. Shingled roofs cost about the same to install here as a tiled roof in the UK, but then here you can't employ labour for much less than $120'ish an hour. I had a sparky who tried to squeeze $2000 out of me as his day rate recently.
